The present invention provides an electrode for a polymer electrolyte membrane fuel cell. In one embodiment, a planar nanoporous or microporous metal foam or metal aerogel structure is provided, from which an electrode with a catalyst layer integrally formed by fixing a catalyst in the metal foam or metal aerogel is formed.

Fuel cell electrode

Disclosed is a method for preparing nickel or palladium nanoparticles supported on a carbon support. To a mixture solution wherein a stabilizer is dissolved in 1,2-propanediol, a carbon support is added to prepare a dispersion. Then, a precursor solution wherein a nickel or palladium precursor dissolved in 1,2-propanediol is mixed therewith and stirred. Then, nickel or palladium nanoparticles supported on the carbon support are prepared by reduction. The disclosed method for preparing nickel or palladium nanoparticles supported on a carbon support allows preparation of nanoparticles with narrow particle size distribution and good dispersibility through a simple process and the resulting nickel or palladium nanoparticles may be usefully applied, for example, as electrode materials of fuel cells.
